Liquid ejecting apparatus and liquid accommodating device

A liquid ejecting apparatus comprising:

• an accommodating container that accommodates a conductive liquid;
• a first electrode accommodated in the accommodating container;
• a second electrode accommodated in the accommodating container;
• a cylindrical partition wall that is accommodated in the accommodating container and is provided to cover at least a part of the first electrode;
• a detection circuitry that is electrically coupled to the first electrode and the second electrode and outputs a detection signal corresponding to an electric signal from one of the first electrode and the second electrode;
• and
• a specifying circuitry that specifies an amount of remaining liquid accommodated in the accommodating container based on the detection signal, wherein
• a first opening through which the first electrode is inserted is formed at an upper surface of the cylindrical partition wall,
• a second opening is formed at a lower surface of the cylindrical partition wall, and
• when the liquid accommodated in the accommodating container is present at the first opening and the second opening, the first electrode and the second electrode are in contact with the liquid accommodated in the accommodating container.
